The Rig Veda Text - Diospitru and Jupiter

Diospitru and Prithuimata are the two parents of all the other gods in the Rig Veda pantheon, which eventually became the pantheon of all the Indo-Europe. So now when it comes to Zeus and Jupiter, so Diospitru became Zeus Pater and Zeus Pater became Jupiter. That's how it went. There is no alternative origin story, this is the story.
